Hi Phoebe,The README is inadvertently describing the examples in CULA Dense. We will correct that.

That said, you can download the free version of CULA Dense to check out that example. While CULA Sparse will not use multiple GPUs to solve a single system, the library can be used to issue separate problems simultaneously to different GPUs. The example code will demonstrate how.

While CULA Sparse will not use multiple GPUs to solve a single system, the library can be used to issue separate problems simultaneously to different GPUs.

Just as you said that CULA Sparse does not use multiple GPUs to solve a single system. So do you have any plan to update CULA Sparse to make it use multiple GPUs to solve a single system in the future? Thanks！

It's likely, but I'll caution that it's not on the immediate horizon. We're still seeking motivating cases for this need - most of our customer problems to date are more effectively solved by a single GPU than by multiple. (ie the overhead of having the GPUs communicate among themselves outweighs the perf gains by using multiple)
